Answer 2

Answer:

The average wage paid by the contractor per day is $21$ rupees.

Explanation:

As per the instructions of the question:

• The contractor employs $20$ men who are paid $25$ rupees per day. So, the amount paid to men in one day is $20*25=500$ rupees.
• The contractor employs $15$ women who are paid $20$ rupees per day. So, the amount paid to women in one day is $15*20=300$ rupees.
• The contractor employs $5$ children who are paid $8$ rupees per day. So, the amount paid to children in one day is $5*8=40$ rupees

So in one day, the contractor spends $500+300+40=840$ rupees. And, the average wage paid by the contractor is $840/40=21$ rupees per day.
